CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 265,773, dated October10, 1882.

Application filed March 11, I882.

To all whom it may concern:

Be it known that I, EDWARD EBI, of Cedar Rapids, in the countyofLinnandState of Iowa, have invented a new and Improved Brake- Rod, of whichthe following is a full, clear, and exact description.

The object of my invention is to provide a new and 1mproved device forapplying all the brakes of a train simultaneously.

The invention consists in a rotating brakerod journaled below thecar'bottom and provided at the ends with clutch-plates longitudinallymovable on the brakerod, whereby the ends of the brake-rods will belocked together automatically when the cars are coupled.

The invention also consists in parts of construction and combinations ofthe same, as will be fully described hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal elevation of a car provided with my'improvedbrake-rod, parts beingbroken and parts shown in section. Fig. 2 is afront elevation of the notched end clutchplate on my improved brake-rod.Fig. 3 is a cross-sectional elevation on line at m, Fig. 1.

Arod, A, extending longitudinally below the bottom of the car,isjournaled in the crosspieces of the trucks in the car-frame or inhangers projecting from the bottom ofthe car. The brake-chain B isattached to a friction-sleeve, .O, loosely mounted on the rod A, whichsleeve G is pressed against a collar or annular ridge, D, of the rod Aby a spring, E. A short rod, F, is coupled by means of a universaljoint,

a. to each end of the rod A, and on each rod.

F a sleeve, G,is mounted, provided atits outer end with a clutch disk orplate, H, having its outer surface provided with a series ofprojections, 1), fitting in recesses between like projections in otherlike plate on the other car. This sleeve G is provided with longitudinalslots 0?, into which a transverse pin, 0, of the rod F passes, so thatthe rod F must turn with the sleeve G; but the sleeve G can movelongitudinally on the jointed rod F. A spring, J, coiled around the rodF, pushes the sleeve G toward the outer end of the rod F. The sleeve Grrests in ring or sleeve K, suspended from the draw-head L by means of achain,

(No model.)

M, and is held to prevent longitudinal movement by a rod, N.

' The rods A. can be rotated by means of gearwheels from theear-axleswhenever thehrakes are to be applied, or by means of some suitableseparate motor or device.

The operation is as follows: If the cars are coupled, the surfaces ofthe disks or plates H will be pressed againsteach other by the spring J.If the projections bot one plate are not in the recesses of the oppositeplate, they will be pressed into such recesses by the springs J as soonas the rods A are rotated. If the projections b of one plate or disk Hare in therecesses of the other plate, the two plates or disks will belocked together, and it one rod A is turned the other rod A will beturned with it. In this manner the rods A of all the cars of a train ofcars can be rotated simultaneously. The springE presses the sleeve (3against the collar D, and the friction produced is sufficient to rotatethe sleeve 0 with the rod A, and thereby the chain B will be wound onthe sleeve 0, and the brakes will be applied. As the sleeves G aremovable longitudinally, they will adjust themselves automatically, andthe springs J will always keep the adjoining surfaces of the two clutchplates or disks [I together. The projections b are preferably madeflaring from the surface of the plate or di k 11 outward, as shown inFig.-1, as 'they will then lock to gether better. are coupledautomatically as soon as the cars are coupled.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the bra ke-rod A, of longitudinally-slidingsleeves G, provided with clutch-plates H on their outer ends,substantially as and for the purpose set forth.

The combination, with the brake-rod A and the jointed rods F, of thelongitudinallysliding and spring-pressed sleeves Gr, provided with theclutch-plates H on their outer ends, substantially as and for thepurpose set forth.

3. The combination, with a brake-rod A, of thejointed rods F, thesleevesG on these rods F, and the clutch plates ordisks H at the ends ofthe sleeves G,substantially as herein shown and described, and for thepurpose set forth.

4. The combination, with the brake-rod A,of

The rods A of the several cars IOO Q mews thejointed sections F, thesprings J, the sleeves G, and the clutch plates or disks H at the endsof sleeves G, substantially as herein shown and described, and for thepurpose set forth.

5. The combination, with the brake-rod A, of thejointed sections F, thesprings J, the sleeves G, provided with clutch plates or disks H, thesleeves K, and the suspending-chain M, substantially as herein shown anddescribed, and for the purpose set forth.

6. The combination, with a brake'rod, A, of the jointed sections F, thesleeves G, provided with clutch-plates H, the springs J, the sleeves K,the chains M, and rods N, substantially as EDYVARD EBI.
